Hi Robert, I confirm that I've put this on my list.
In the meantime I suggest you take the manual addition approach and add it this way:
http://iubenda.com/dashboard > edit/add privacy policy > add service > create custom service
more info about custom services can be found here: https://www.iubenda.com/en/help/posts/386
I will update this thread with more information as I have it. Hope this helps?
Simon
